i think i may have a yeast infection. I have thick white discharge, i am itchy and i think there is a smell. I took antibotics on Dec 11, 2008 for 10 days. I am alos on Birth control patch, i missed almost a week of my first patch. I had my last period on Dec 19, 2008. I don't know when my next cycle is because i am inconsistant with the batch missing a few days here and there for the past two months. I range between 28-35 days. I was told when i took the antibotics to use another form of birth control until my next period. I was on amoxiclin, i waited a week after i finished the 10 days. Do you think i am pregnant, and is it related to my yeast infection? or do you think that my yeast is not related to pregnancy and that it will be okay to take over the counter medicine for the yeast.
